Volete visualizzare un elenco di post correlati sul vostro sito WordPress e preferite usare il codice piuttosto che un plugin?
Noi di WPBeginner sottolineiamo spesso l’importanza di coinvolgere il pubblico e di fargli esplorare i contenuti. Una strategia efficace che abbiamo visto utilizzare in innumerevoli siti WordPress di successo è la visualizzazione dei post correlati.
Quando i visitatori del vostro blog hanno finito di leggere un articolo di loro interesse, offrire un elenco di post correlati li terrà impegnati e li aiuterà a trovare nuovi contenuti da leggere.
In questo articolo vi mostreremo come visualizzare gli articoli correlati con WordPress utilizzando il codice, senza bisogno di plugin richiesti.
Perché mostrare le pubblicazioni correlate in WordPress?
Quando il vostro blog WordPress inizia a crescere, può diventare più difficile per gli utenti trovare altri articoli sullo stesso argomento.
Visualizzare un elenco di contenuti correlati alla fine di ogni articolo del blog è un ottimo modo per mantenere i visitatori sul sito web e aumentare le pagine viste. Inoltre, contribuisce a migliorare la visibilità delle pagine più importanti, visualizzando i contenuti migliori dove gli utenti possono trovarli facilmente.
Se non avete dimestichezza con il codice, allora sarà più semplice scegliere uno dei tanti plugin per i post correlati di WordPress, in grado di visualizzare gli articoli correlati senza codice.
Ma se vi siete mai chiesti se sia possibile visualizzare i post correlati senza usare un plugin, condivideremo due diversi algoritmi che potete usare per generare post correlati con immagini in evidenza usando solo il codice:
Nota: se si desidera mostrare un’immagine in evidenza per ogni articolo correlato, assicurarsi di aggiungere prima un’immagine in evidenza a tali articoli.
Metodo 1: come mostrare gli articoli correlati in WordPress in base ai tag
Un modo efficace per individuare i contenuti correlati è cercare altri articoli che condividono gli stessi tag. I tag sono spesso utilizzati per concentrarsi sui dettagli specifici contenuti in un articolo.
Tenendo conto di ciò, è possibile aggiungere alcuni tag comuni agli articoli che si desidera mettere in relazione tra loro. Potete inserirli nel box “Tag” dell’editore di WordPress.
Dopo aver aggiunto i tag agli articoli successivi, la cosa da fare è aggiungere il seguente frammento di codice al template single.php del tema.
Se avete bisogno di aiuto per aggiungere codice al vostro sito, fate riferimento alla nostra guida su come incollare snippet dal web in WordPress.
$orig_post = $post;
global $post;
$tags = wp_get_post_tags($post->ID);
if ($tags) {
$tag_ids = array();
foreach($tags as $individual_tag) $tag_ids[] = $individual_tag->term_id;
$args=array(
'tag__in' => $tag_ids,
'post__not_in' => array($post->ID),
'posts_per_page'=>5, // Number of related posts that will be shown.
'ignore_sticky_posts'=>1
);
$my_query = new wp_query( $args );
if( $my_query->have_posts() ) {
echo '<div id="relatedposts"><h3>Related Posts</h3><ul>';
while( $my_query->have_posts() ) {
$my_query->the_post(); ?>
<li><div class="relatedthumb"><a href="<?php the_permalink()?>" rel="bookmark" title="<?php the_title(); ?>"><!--?php the_post_thumbnail(); ?--></a></div>
<div class="relatedcontent">
<h3><a href="<?php the_permalink()?>" rel="bookmark" title="<?php the_title(); ?>"><!--?php the_title(); ?--></a></h3>
<!--?php the_time('M j, Y') ?-->
</div>
</li>
<!--?php }
echo '</ul--></ul></div>';
}
}
$post = $orig_post;
wp_reset_query();
Questo codice cerca i tag associati a una pagina ed esegue una query del database per recuperare le pagine con tag simili.
Dove posizionare il codice? Dipende dal tema, ma nella maggior parte dei casi si dovrebbe poter incollare il codice nel template single.php del tema dopo l’articolo principale e proprio sopra la sezione dei commenti.
Se si utilizza il tema Twenty Twenty-One, come nel nostro sito dimostrativo, un buon posto dove incollare il codice è il file template-parts/content/content-single.php dopo l’header e subito dopo <?php the_content();.
Questo visualizza automaticamente i contenuti correlati su qualsiasi articolo di WordPress. È necessario modificare lo stile e l’aspetto degli articoli correlati in corrispondenza del tema aggiungendo CSS personalizzati.
Suggerimento: invece di modificare i file del tema, che potrebbero danneggiare il sito web, si consiglia di utilizzare un plugin per gli snippet di codice come WPCode.
WPCode rende sicura e facile l’aggiunta di codice personalizzato in WordPress. Inoltre, è dotato di opzioni di “inserimento” che consentono di inserire ed eseguire automaticamente gli snippet in punti specifici del sito WordPress, ad esempio dopo un articolo.
Per maggiori dettagli, consultate la nostra guida su come add-on di codice personalizzato in WordPress. Potete anche consultare la nostra recensione dettagliata di WPCode per approfondire chi siamo.
Metodo 2: Come mostrare articoli correlati in WordPress per categoria
Un altro modo per visualizzare i contenuti correlati è quello di elencare gli articoli che appartengono alla stessa categoria. Il vantaggio di questo metodo è che l’elenco degli articoli correlati non sarà quasi mai vuoto.
Come per il metodo 1, è necessario aggiungere uno snippet di codice al template single.php del tema o in un plugin di snippet di codice come WPCode. Per maggiori dettagli, fare riferimento al Metodo 1 e alla nostra guida su come add-on di codice personalizzato in WordPress.
$orig_post = $post;
global $post;
$categories = get_the_category($post->ID);
if ($categories) {
$category_ids = array();
foreach($categories as $individual_category) $category_ids[] = $individual_category->term_id;
$args=array(
'category__in' => $category_ids,
'post__not_in' => array($post->ID),
'posts_per_page'=> 2, // Number of related posts that will be shown.
'ignore_sticky_posts'=>1
);
$my_query = new wp_query( $args );
if( $my_query->have_posts() ) {
echo '<div id="related_posts"><h3>Related Posts</h3><ul>';
while( $my_query->have_posts() ) {
$my_query->the_post();?>
<li><div class="relatedthumb"><a href="<?php the_permalink()?>" rel="bookmark" title="<?php the_title(); ?>"><!--?php the_post_thumbnail(); ?--></a></div>
<div class="relatedcontent">
<h3><a href="<?php the_permalink()?>" rel="bookmark" title="<?php the_title(); ?>"><!--?php the_title(); ?--></a></h3>
<!--?php the_time('M j, Y') ?-->
</div>
</li>
<!--?php }
echo '</ul--></ul></div>';
}
}
$post = $orig_post;
wp_reset_query();
Ora vedrete un elenco di contenuti correlati in fondo a ogni articolo.
Se si desidera modificare lo stile e l’aspetto delle pagine correlate, è necessario aggiungere CSS personalizzato in corrispondenza del tema.

amazing post ,, thanks
shaileshtr
It is good to show related post in wordpress blog without plugiN. iIt will consume less bandwidth and time to load. http://shareitto.com Thanks for your suggestion.
zioneyemedia
I do have a question on this: I’m wrestling on the code to capture posts from child categories versus parent categories. Any advice?
AmandaLong
This rocks … Thanks!
dustinporchia
I’m trying to use the related posts by category and I noticed that you said the code has to come before the comments in the main loop. In my code I want the related posts to come after the comments in the loop. When I do this I notice my disqus comment plugin takes longer to load now. Is that because of an error with the comments or is that normal?
dustinporchia
Nevermind…I just switched to livefyre as this is more of what I’m looking for in a comment system anyways…thanks!
subzerokh
please
could someone help a newbie like me customize this script so it’ll display related post in an horizontal way?
from left to right..
instead of currently showing it from up to down, vertically…
zioneyemedia
Hey,
How I did it is I replaced the and codes with my own html and css. The codes create lists for each post, and that is usually in a vertical fashion.
——————
<a href="” rel=”bookmark” title=””> <a href="” rel=”bookmark” title=””>
——————
I replaced the opening with and replaced the closing with as my html tags. Then I write my CSS to fit that specific div class needs on your website. For example, a sample pleft class could look like this:
.pleft {float:left; padding:2px; margin:10px; width:278px; height:190px;}
I use the float: selector on my CSS to move posts horizontally, and the margins and padding to give each post spacing within each other. I added in a specific width and height for additional examples.
Hope this helps.
Simos
@zioneyemedia thank you!
gcog
I’ve got related tags for sure, but when I add the code I see nothing. Also, when I add your code to restrict to a custom post type, it gives me an error. I did change the post type to my specific post type.
subzerokh
@wpbeginner hello
thanks for your quick answer…
but i’m a real novice at all you are saying..
can you please give a litlle exemple?
for making them horizontal as on your own blog?
can get in touch by my mail: khiloc at gmail dot com
wpbeginner
@subzerokh You would have to edit the styling. It is not that hard. Simply wrap each post in a div. Specify a width for that div and then set a float left property. Adjust the margins and such and you have it.
subzerokh
hello all!! thanks for this wonderfull script!!
It’s the only thing i found doing exactly what i wanted!!!
But it’s just showing related post in vertical way (from up to down)
I would like it to be shown from left to right (horizontally)
How to do that please??

Can I have a CSS For this please
Editorial Staff
The CSS we used was for a client’s site. You can add your own CSS on how you want to display this.
Admin
titusmagnet
Thanks..im searching for this kinda Code
jaffa
This is great, just what I have been looking for. I wonder though, how could I combine the two above and if there are no tags then it displays posts from the same category?
Trying to figure this out but not getting very far yet
nikbanks
Thanks for the code it worked but how do I style it. I’d like it to be 4 stories side by side like yours. It is listed one on top of another on my site and not listed like yours.
Editorial Staff
That is CSS. We are not using this code to show related stories. Second, i believe what you are talking about is featured stories on our sidebar. We have written another post about that in our site.
Admin
Coolguy
is ther a way to dispay the thumbs in related post without using featured images or post thumbs??
i.e to use any image used in the post …
Editorial Staff
Yes, you can utilize the fallback techniques shared by other developers which pulls the first image from the post. But we recommend using the WordPress post thumbnails…
Admin
Hetal
Thanks for this article. I was wondering if there is a way to auto-tag posts without having to manually enter them.
Editorial Staff
No you have to tag each post manually.
Admin

Great!
What if I want to display related posts by category without thumbnails?
Thanks

Just remove the thumbnail code from the code above

Hi there…Just wanted to say that I’ve been building my wordpress website from the ground up and this code works perfectly for me using WP 3.1….All I need to do now is style the CSS and get some thumbnails happening for the posts. Thanks for your help with the code.
new car release
thanks, i’m looking this hack for so long and you got it to me!
Patricia
Hi, is there a way to exclude categories? I have two main categories where all the categories get assigned to. The main categories have sub-categories and I would like to show just related posts from the sub-categories.
Is this possible, by excluding the id’s of the main categories?
Thanks for your advice!
BTW…love the code…and it works great!!!
Editorial Staff
You should be able to use category not in <<
Admin
usman
I was searching for related post with thumbnails plugins but the code that you paste above, solve my problem.
John
Just one question, is there a way to only pull tags from the same post type? Maybe using something like ‘post_type=videos’?
John
By the way, got this figured out as well:
Just add it to the array:
$args=array(
‘category__in’ => $category_ids,
‘post__not_in’ => array($post->ID),
‘posts_per_page’=> 2, // Number of related posts that will be shown.
‘caller_get_posts’=>1,
‘post_type’=>’videos’
);
marion
Hi,
Thank you for this tutorial. I’m wondering though if there’s anyway the related products can be randomized? I’ve checked different products in the same category and the same related products were shown.
Thanks
Editorial Staff
Yes use the Query_Post parameter for order and you can randomize it.
Admin
Clarence Johnson
Good to know.
phdean
Hi,
I too would like to randomize the posts that display for the categories as, otherwise, they’ll display the same 2 every time. Can you please give me the code to do this?
Many thanks in advance
John
Nevermind, I got it figured out. Thanks for the post!
Editorial Staff
what was the issue?
Admin
John
I didn’t have any other posts with the same tags, i.e. no related posts. Dummy mistake.
John
I copied this code and put it in my single.php without changing a thing and nothing gets outputted. Anything wrong with my code? pastebin.com/kg0SkrAg
James
This doesn’t bring up a thumbnail — there isn’t even a call for an image int eh code. I don’t see how anyone can get this to work.
Editorial Staff
The code for the image is: the_post_thumbnail(); << This is not static html where you will see img src code. The function calls in the database to search for a featured image aka thumbnail that is attached to each article. If found, it will output the image. Now if you do not have post thumbnails enabled in your theme, then you need to add it first:
https://www.wpbeginner.com/wp-themes/how-to-add-post-thumbnails-in-wordpress/
The article clearly stated that in the Note: section. You should consider reading it thoroughly.

Roberto Silva
hey man, I love your blog!
I have a question?
Can you do the same trick but ” BY Author” ?
showing the latest posts by author?
you will save my life
Btw thanks for this website!
Editorial Staff
Yes we will que the article soon
Admin
Roberto Silva
yessss, thanks…
It will be a great article.
bacause “latest posts by author without plugin” is hard to find on internet.
you are the best.
Quinn
Thanks for this code! I’ve given it a try and it works somewhat.
I can get it to give a listing of the related articles, a huge benefit.
But I can’t seem to get any images to show up.
The articles have images if this code scrapes.
I also went in and created images for each post with the custom tag “relatedthumb”. But alas, still no images.
Is there something else I need to do?
Many thanks in advance!
Quinn
Editorial Staff
This trick is using the default WordPress thumbnails which was added in WP 2.9. If you have an image attached as that thumbnail, then it will pull it.
Admin
Anthony
Is it possible to exclude a category from this module ?
Thanks a lot,
Anthony
Editorial Staff
It will only shows post on the category that the other post resides in…

I’m trying to modify his code in order to use it with categories within a custom post type. Can anyone help? I’m fairly new to php.
Thanks!
rulethenation
ok i got it to work, is there anyway to put a default pic if a thumbnail is unavailable
Editorial Staff
Yes, you can use the if paramter to check if there are plugins… if not then you can display a default image.
Admin
rulethenation
how would i go about doing that? im a php noob lol
Quickbrown
In order to use default images when no post thumbnail available, replace with <?php if (has_post_thumbnail()) {the_post_thumbnail()} else {echo '’;} ?>
Then put a default-image.jpg under your themes’ image folder.
rulethenation
i cant get this to work, it just messes up my whole layout near the comments, am i missing something? i had to take it off my site

My posts are now enriched thanks to you and this tutorial.

HI!
Thanks for this information! This is exactly what I was looking for.
Is there a way to add an excerpt to this, along with the photo?
Thanks again for your help!

Yes. Just add the_excerpt(); where you want it to display excerpt.
Admin
Jez
Thanks for this, exactly what I was looking for! I love how straight to the point your articles are, no confusion.
Omer Greenwald
Thanks for sharing. I’m using this code for a while now but it has a problem: when adding tags to a post, WP sorts them alphabetically regardless of the priority I added them. So this code displays related posts matching the first tag only which are less relevant sometimes.
Maybe you have an idea how to prevent this auto sorting of tags by WordPress or any other solution?
Editorial Staff
It is not using the first tag. This code is using all tags from the posts to find related posts.
Admin
Clarence Johnson
I’m experiencing the same issue too.
Doug C.
All that first code did was put two instances of the same post on the page. It didn’t show any related anything.
Editorial Staff
Doug please contact us using the form with a live link example, and we can help. We know this code is working because a few of our client’s site is using it.

Great tutorial. Would someone mind showing me a working single.php with this code?
I’m still learning php.
Unfortunately
Parse error: syntax error, unexpected T_ENDIF in C:\xampplite\htdocs\mock\wp-content\themes\scwd\single.php on line 76
Editorial Staff
Here is a working example Flowtown Blog.
Note that this code is so it will work inside the loop. Where are you trying to post this? If it is outside the loop then just add the end if code endif; << like that.
Admin

I hope the link works. Thank you.
Editorial Staff
Don’t know what could be going wrong. After the clearfloat class it should work fine. That is how we put it in flowtown and it is working perfectly.
Liam
I will finish the theme and try it on a live site instead of xamp. I will let you know.
